    Picked up a NOS Dyna-Flyte 406-D conversion plate for my Plymouth, as well as the correct autolite point set, and a autolite condenser for the original distributor, a Autolite AIT-4101 from 1953, that I am almost done rebuilding.

    Conversion plate did not include instructions. Anyone have something similar that shows what the little plate and hardware is for? Points sit the same as in a Mopar V8 dual point distributor, I don't think the condenser will fit inside the cap.

    Grease in the ball bearing was rock hard, and I have a little more work to do to get it clean out the rest of the way, but what should I use to relube it? Not much room to repack any sort of grease back in. May get some in from the back side, but I doubt it. Will a few drops of motor oil do it? Something thicker? Lighter?

    Any random history or info about the Dyna-Flyte brand is welcome too.

    that looks like fun! The bracket must mount the condenser outside the distributor. A drop of motor oil should be fine for lube. Remember to oil it again every year. Did you figure out how the points fit on it, etc?

    I think I understand how the points fit. Typically is there a lock washer under the screw that hold the points in place?
    Not quite sure how the jumper wire is supposed to attach, only one of the cardboard covered posts has a screw built in.

    On the P15 forum I found a post by Don Coatney where he shows the directions and his same kit.

    Looks like I am missing a few pieces...
    A few over there were suggesting that I could press the plate apart, but it seems crimped together.l, and I worry about damaging it. Anyone take something like this apart?

    I would soak the breaker plate in a solvent to dissolve the grease then thoroughly dry and lubricate with a small amount of motor oil. These ball bearing dual point breaker plates were a common replacement item back in the day. The ball bearings gave a more stable support and the dual points gave a better spark than the single points.

    Try contacting GMC BUBBA. Might even help locating any missing pieces too.
